Abstract
Switchable multi-antenna fluid sensing systems and methods, including a tubular-mounted switchable multi-antenna fluid sensing system that includes two antenna arrays that each senses fluid characteristics not sensed by other antenna arrays, each array including multiple antenna sub-arrays and each sub-array including a receive and transmit antenna with a radial transmission direction different from that of other sub-arrays. The system also includes two RF multiplexers, each coupled to the antennas within the arrays and to corresponding RF transceivers within a sensor tube. A CPU within the sensor tube couples to the RF transceivers, controls signal transmission by, and processes received signals from, the antennas. RF cables coupling the RF transceivers and RF multiplexers are grouped and routed through one end of the sensor tube. The CPU further causes the RF multiplexers to periodically couple to the antennas and stores and/or transmits data representing the received signals.
